ABSTRACT:
A Self-Timed Pulse Control circuit and operating method is highly useful for adjusting delays of timing circuits to prevent logic races. In an illustrative example, the STPC circuit is used to adjust timing in self-timed sense amplifiers. The Self-Timed Pulse Control (STPC) circuit is integrated onto an integrated circuit chip along with the circuit structures that are timed using timing structures that are adjusted using STPC. The STPC is also advantageously used to modify the duty cycle of clocks, determine critical timing paths so that overall circuit speed is optimized, and adjusting dynamic circuit timing so that inoperable circuits become useful.
